.TO ALL WHOM IT MAY vCONCERN:

Be it known that we, PJIILLU Esser. and FRANKLIN A. Smarts, both ofNorth Providence, in the county ot' Providence, and State of RhodeIsland, havev invented a new and improved Machine for SettngButton-Hooks; and we do hereby declaro thatv the following specification, takenin connection with the drawings, making a part of the same, is a full,clear, and exa'ct description thereof. i

Figure 1 exhibits the machine'in perspective. 4 u

Figures 2, 3, and 4 are detailed parts to be referred to.

Our machine is designed to adord a means forconveniently inserting inshoes and gaiters that article known as a combined hook and button,which is described and shown in the Letters Patent granted to William H.Shurtleff, of Providence, Rhode Island, dated dune 5, 1856, and which,for holding laeing's for shoes and like purposes, is intended tosupersede the use of eyelets.

The drawing represents a hand-tool, but the same principles which areemployed in it can be equally well embodied in a 'machine to be operatedby power. 4 i

The article referred toas a combined hook and button consists ot ametallic button-head set upon a crooked neck, and furnished with threeprongs, which prongs are intended to be inserted in the material towhich the article is to be aiiixcd, and clinched upon the back sidethereof, leaving upon the Aface sideof the material in sight only thecrooked neck surmounted by a. button-head. d i

In the particular instance shown in the drawings, A A arejaws heldtogether by a pivot-pin, a, and being intended for a hand-machine, arefurnished with handles like a pair of well-known pliers. The upperjawmay 1 he furnished with an adjustable stop, Z1, or other convenientdevice for limiting the distance within which theV jaws can he opened.The vlower jaw is furnished with a sided block, B, having threerectangular faces of equal size, and two sides in the form ofequilateral triangles. Thev cud'` of the lower jaw A. is made forked,and the block is mounted in the opening formed by the forks, so thatitcan be revolved upon a pin, c, passing through the sides of the fork andthe triangular faces of the block.

A spring-pawl, d, fig. 4, is attached to the upper jaw, and is soarranged with reference to the block B that upon opening thejaws A A totheir full extent the block will be made to turn one-'third ofa completerevolution upon its axis, while. during the movement of thejaws, vinclosing, the 'dat face of the spring-'shank of v'the l pawl will bearagainst one ofthe sides of the block, and hold'it in that position untilthe next movement of the jaws in opening.

The several faces of the block are as shown in figs. 2, 3, and 4. Thefirst is provided with three holes corresponding in position and indepth with the arrangement and length of the three prongsof thebutton-hook, as `shown in iig. 1. The second face is furnished with adepression in the form of a segment of a hollow sphere. The third facepresents a smooth surface. i l

The operation of' the apparatus is Vas follows: The buttonhook is hungby its neck in the receptacle E, especially made for the purpose, luponthe upper jaw, that face of the block B being` uppermost which is iur*nished with holes corresponding in number and arrangement tothe prongsof the button-hook.

The piece of leather or other material to which the button-hooks are tobe attached is now held in position and the jaws are made to close. ThisAcauses the-sharp prongs ot' the button-hook to pierce the material, andbeing forced through it protrndes beyond the under side, the button-hookbeing all` the time retained in the receptacle E.

The next movement of opening the Yjaws causes the protruding ends oftheprongs'to be withdrawn from the holes in the hlck,"and the block itselfto be rotated, so as to cause the face shown in fig. 2 to be uppermost.The next movement of thejaws in closingbends the ends of theprongsinward toward a common centre.- The jaws being again opened, the blockis again rotated, so that its smooth face is uppermost, when, the jawsbeing again made to approach each other, the ends of the prongs arepressed clown at against 'the under surface of the material, and thebuttonfhook is securely s et. I

I Upon opening the jaws for the'last time, prior to disengaging` fromthe apparatus the buttowhool; which has jilst been set, tl1-e block isagain rotated, so as'to present uppermost the face shown in iig. Il, andready for a repetition of the rst operation to be performed in setting,`the next hutton-hookin the jaws.

What we claim as our invention, and -clesire'to secure by LettersPatent, 'is

1. A machine for setting button-holes, consisting of a revolving block,B, with acting faces, as described, in combination with` the spring-paulci' andjaws A A, operating substantially as set forth. v

2. Constructing the jaw A with a receptacle, E, for the button-hook, soas to hold and' sustain the same While it is being inserted and itsprongs clinched, substantially as shown ancl is worked. l
